PORTER 4222 AUTOMATIC CHANGEOVER MANIFOLD SYSTEM The system that monitors and switches to your reserve tank when your primary tank is empty, all of which is accomplished automatically with only the gas serviceman maintaining the gas supply and tank status light entry condition by pushing the gas service acknowledge button located on the manifold. IMPORTANT FEATURES TO KNOW ABOUT THE PORTER AUTOMATIC CHANGEOVER MANIFOLD HOW THE SYSTEM OPERATES Make sure oxygen and nitrous oxide tanks are hooked-up and turned ON. Regulators must be set at 50 PSIG regulated pressure to insure normal operation. At alarm station PUSH (GAS / OFF) button to start up system. The alarm should indicate normal line pressure condition lights and the tank status light should lock on tank position 1 or 2 after a few seconds. NOTE: It is important to know that on initial start-up of your manifold system, when there is no pressure in the lines, it may require the service acknowledge button on the manifold to be depressed several times to allow the manifold to switch back and forth between tanks to initially fill piping system to the 50 PSIG level. If pressure in the system is at 40 PSIG or below, the alarm will indicate a low-pressure light and audible tone. If a reserve tank is available, the manifold will switch over automatically after 10-20 seconds of low status to the reserve tank. The low-pressure light and audible tone will change to the normal light when the pressure reaches the safety zone. Normal line pressure is 50 PSIG (gauge observable on the manifold). The tank that is now empty and off-line will indicate a flashing light signal at the alarm and manifold. This condition will remain until the service acknowledge button on manifold is depressed to turn OFF flashing signal. This should be done only when the gas supply is replenished by the gas service man. System must be ON to reset tank at service acknowledge button. Now your tank status lights should indicate one light ON and one light OFF indicating primary tank is in use and reserve tank is available for back-up. FAILSAFE IN MANIFOLD The 4222 manifold has a built-in failsafe feature. For your patients safety, the manifold will not deliver nitrous oxide through to the piping system if oxygen supply pressure is depleted or turned off. 7
WIRING IN MANIFOLD SYSTEM The alarm connection to the system is accomplished by either a two foot length modular male connector cable that connects to a plug-in terminal block, for the Wall Mount version, or a ten foot length modular male connector cable that connects to the signal interconnect assembly, for the Desk Mount version. From this point through to the manifold, all connections for transferring DC power and signal is carried through the four-conductor alarm cable. The colored wires in the alarm cable must terminate to the same terminal throughout the system. Terminal 1 (Red) carries DC power to system. Terminals 2 (Green) and 3 (White) carry signal for changeover. Terminal 4 (Black) is a power ground. Voltage reading (12 Vdc ± 2 Vdc) should be taken with voltmeter negative ( - ) on #4 (Black) ground, voltmeter positive ( + ) on #1 (Red). Voltage at terminal 2 (Green) is nominally +1.5 Vdc and at terminal 3 (White) is nominally +0.4 Vdc. SHUT-OFF OPERATON Depress the OFF button. Alarm beeps 3 times and all lights flash before shutting down. SILENCE BUTTON The silence button is used to turn OFF the audible alarm condition. NORMAL OPERATION INDICATIONS FOR ALARM STATION 1. The yellow LED flashing and one short beep indicates that the oxygen or nitrous oxide line pressure(s) is below 40 PSIG. 2. The red LED flashing and two short beeps indicate that the oxygen or nitrous oxide line pressure(s) is above 60 PSIG. 3. Four beeps indicate that the system has a hardware problem, usually signifying that a pressure switch has failed. 4. Five beeps indicate that the alarm has lost communications with the manifold and that the alarm is no longer indicating the status of the oxygen and nitrous oxide tanks. 5. The green LED light indicates that the line pressure is at normal pressure. 8
FUNCTION TESTING CHANGEOVER MANIFOLD Initial Start-up and Testing Procedure 1. Make sure oxygen and nitrous oxide tanks are hooked up and turned ON. Regulators must be set at 50 PSIG regulated pressure to insure normal operation. 2. At Alarm Station PUSH (GAS / OFF) button to start up system. 3. The alarm should indicate normal line pressure condition lights and the tank status light should lock on tank position 1 or 2. NOTE: It is important to know that on initial start-up of your manifold system, when there is no pressure in the lines, it may require the service acknowledge button on the manifold to be depressed several times to allow the manifold to switch back and forth between tanks to initially fill piping system to the 50 PSIG level. 4. Now that the piping system is filled and the manifold has conducted its initial start-up function, it must be checked for its automatic changeover capability. 5. Steps to Check Tank Switching Process 5.1. Turn down set pressure on primary tank regulator to 35 PSIG (note how much of a turn is made on regulator adjusting stem) while bleeding down system pressure through dental meter at 5 L/min rate of flow. 5.2. At 40 PSIG the manifold will announce an audible and visual alarm condition for 10 to 20 seconds and switch to reserve tank. The manifold will shut the primary solenoid and open the reserve solenoid, which will deliver gas at 50 PSIG and signal the normal light. After changeover has occurred, reset regulator on Tank #1 to original condition position 50 PSIG. 5.3. Manifold display panel and alarm will show a blinking light at the primary tank location. 5.4. Push service acknowledge button on manifold to turn OFF blinking light at Tank 1 location. 5.5. Reverse the procedure to switch back to Tank #1. Turn down pressure to 35 PSIG on reserve regulator while continuing to flow gas at 5 L/min downstream at a dental meter. Manifold will again announce alarm condition and switch back to primary tank. Reset Tank #2 regulator back to 50 PSIG setting. 5.6. Push service acknowledge button on manifold to turn OFF blinking light at Tank 2 location. 5.7. Repeat this process for both oxygen and nitrous oxide. 9
TROUBLE SHOOTING Symptom Possible Cause / Remedy 1. Tanks will not changeover. Defective pressure switch will not create a low-pressure signal to produce changeover response. 2. Tanks change over before tanks are empty. This may result from piping system having a leak and bleeding down pressure over night. Tank pressure will remain the same due to the manifold and alarm system being turned OFF and holding cylinder pressure stable. Inspect line pressure in the morning for setting to remain between 45 to 55 PSIG. 3. System has no lights. Remove cover on Power/Signal Junction Assembly (Refer to page 4) and check if Red LED indicator is on to show power supply is working. Defective OFF / Button, or electronics. Contact Porter for further assistance. 4. Tanks change over, but pressure does not come up to 50 PSIG. Check regulator for correct pressure setting. DISS inlet fitting has a check valve stuck shut restricting pressure. Depress or hold service acknowledge button to fill system to bring up line pressure. Defective solenoid prevents pneumatic circuit from opening for delivering line pressure. 5. The yellow and red LEDs are flashing and the unit is beeping four beeps. The pressure switch is defective on the gas for which the yellow and red LEDs are flashing. Replace the pressure switch. CAUTION Static Damage Hazard: Computer and other electronic components can be permanently damaged by static electric discharge. Use caution when working with the molded manifold cover off, especially in the area of the RESET1 button. 6. Lights Flashing; locked into a random flashing pattern. Caution, carefully depress Reset1 button only on manifold. (Refer Caution above and page 6.) Defective electronics or timing problem. Contact Porter for further assistance. 7. Alarm will not silence. Caution, carefully depress Reset1 button only on manifold. (Refer to Caution above and page 6.) Defective electronics or timing problem. Contact Porter for further assistance. 8. Cannot turn OFF system Caution, carefully depress Reset1 button only on manifold. (Refer to Caution above and page 6.) 10
